Description
The KSZ8842-16MQL and KSZ8842-32MQL are the
industry’s rst 2-port switches with a non-PCI CPU inter-
face. The KSZ8842-16MQL (or -32MQL) is a proven, 4th
generation, integrated, Layer 2 switch that is compliant to
the IEEE802.3u standard.
The KSZ8842-16MQL (or -32MQL) can be congured
as a low-latency repeater to allow for ‘cut thru’ in latency
critical Embedded or Industrial Ethernet applications. For
industrial automation applications in the repeater mode, the
KSZ8842-16MQL (or -32MQL) runs in half-duplex mode
regardless of the application.
The KSZ8842-16MQL (or -32MQL) offers an extensive
feature set that includes tag/port-based VLAN, QoS priority
management, MAC ltering function, MIB counters, and
CPU control/data interfaces to effectively address both
current and emerging Fast Ethernet applications.
The KSZ8842-16MQL (or -32MQL) contains two 10/100
transceivers with patented mixed-signal low-power technol-
ogy, two media access control (MAC) units, a direct memory
access (DMA) channel, a high-speed non-blocking switch
fabric, a dedicated 1K entry forwarding table, and on-chip
frame buffer memory.
